Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned nicolasestrem/antigravity-gemini-skills at 5816ff4d9f.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill enables an AI agent to design, implement, and debug WebSocket servers and clients. It facilitates real-time bidirectional communication between applications, allowing for features like live data updates, chat functionality, and interactive dashboards. The skill provides expertise in handling connection management, message routing, and error handling within a WebSocket environment.

When to use it

  • Building Real-Time Applications: Develop applications requiring instant data synchronization, such as collaborative editing tools or live scoreboards.
  • Creating Chatbots & Messaging Systems: Implement robust chat interfaces with persistent connections and efficient message delivery.
  • Developing IoT Solutions: Facilitate communication between devices and a central server for monitoring and control purposes.
  • Implementing Live Data Feeds: Create dashboards that display real-time data streams from various sources, such as stock prices or sensor readings.

Key capabilities

  • WebSocket Server Design & Implementation
  • WebSocket Client Development
  • Connection Management
  • Message Routing
  • Error Handling

Example prompts

  • "Implement a WebSocket server to handle chat messages between users."
  • "Create a client that connects to a WebSocket endpoint and displays live data updates."
  • “Debug this WebSocket connection error; the client is unable to establish a persistent connection.”

Tips & gotchas

This skill requires a foundational understanding of networking concepts. Be prepared to provide specific details about the desired WebSocket protocol version, message format, and server infrastructure.
